T-Rex Allegedly Has a Smart Brain Beyond Human Conjecture, Can Build Culture

JAKARTA – The dinosaur T-Rex turned out to have brain which is very enough to make equipment, solve problems, to build culture. So if the asteroid that hit Earth and wiped out the dinosaurs didn’t happen, it could be that T-Rex has made a long cultural history.

According to Suzana Herculano-Houzel, a researcher from Vanderbilt University, this ability was formed because the brain of the T-Rex had a very large number of neurons in the cerebrum or cerebrum. He estimated that the number of neurons present in the theropod cerebrum was equal to the number of neurons present in the cerebrum of monkeys.

It is estimated that theropods such as Alioramus had as many as one billion neurons in the cerebrum. The T-Rex actually has a very large number with a total of three billion neurons in the cerebrum.

According to Suzana Herculano-Houzel, if the number of neurons reflects the intelligence of eating, these prehistoric animals not only had giant sizes, but also lived long lives and had flexible cognition. It means T-Rex would be a more formidable predator than previously thought.

“An elephant-sized but agile carnivore endowed with cognition like an ape or a baboon must have been a very competent predator,” he explained.

According to Suzana Herculano-Houzel, counting the number of neurons in the cerebrum was done by counting neurons in birds. According to him, the birds that exist today are the last descendants of the dinosaurs.

“Birds are descended from dinosaurs that lived much longer. Birds are still dinosaurs,” he explained.

He continued that currently the concept of counting brain neurons tends to be misguided because many consider all dinosaurs to be the same. Though dinosaurs are different from each other. “Just like mammals, not all are the same. T-Rex and some other dinosaurs apparently had the same brain size as birds. That means it can be counted,” he explained.

From there, Suzana Herculano-Houzel made a calculation using the size of a bird. The result is the number of brain neurons owned by T-Rex is the same as the number of brain neurons in primates.

“An elephant-sized but agile bipedal carnivore endowed with cognition like an ape or a baboon must have been a very competent predator,” he stressed.
